摘要： A method in a paper or board machine for confining a pulp flow coming from the headbox (1), in which by at least one deckle part (2) being above the wire in the operating position the pulp flow coming from the headbox is confined in the lateral direction in the edge area of the wire (3). In the method, by a support part (50) impervious to liquid being below the wire (3) together with the deckle part (2) into connection with which liquid is brought, a pressure effect is provided which furthers the sealing between the deckle board (2) and the wire (3) and intensifies the lubrication of at least one sealing surface of the deckle (2). The invention also relates to an apparatus.
